Application filed November 14 1 338. S ,e,ria1 3,123,384.

My saidinvention relates to improvements in attachments for the outletfines of gas stoves designed to prevent the escaping gases and dustladen products of combustion from soiling or disfiguring walls adjacentthe stove. I

The invention aims to provide an article capable of being soeconomically made that it can be sold at a profit in the ordinary fiveand ten cent stores, and which will be eifi- Y cient in operation, andwhich will be readily attachable to any stove irrespective of the sizeof flue outlet.

lVit-h these objects in view the invent on includes the novel featuresof construction and arrangement and combination of parts hereinafterdescribed and defined by the appended claims.

In order that the invention may be better understood, reference is madeto the accompanying drawings in which: I

Figure 1 is an elevation showing what I at present consider thepreferred form of the 111- vention as applied to the collar, ring, orflange which forms the outlet of the usual ventilating flue, a portiononly of the gas stove top being shown in a conventional manner forconvenience of illustration.

Fig. 2 is a plan view.

Fig. 3 is a perspective vlew of the supporting frame with the hood ordeflector re moved.

Fig. 4 is a similar View of a modified form of supporting frame, and

Fig. 5 is a plan View of a modlfied form of hood top plate.

Referring by reference characters to these drawings, the numeral 1designates the gas stove top and 2 the collar or ring of the outlet fiuethereof. 3 designates the hood of the deflector which is of elongatedtruncated cone shape and is preferably formed of two sections of sheetmetal stamped to the proper curved shape and having their end edgessuitably connected as for example by joints 3' of the interlocking foldtype.

The lower edge of the deflector is preferably provided with areinforcing bead 3 formed in the stamping operation.

'The parts are so r ena iti'ned tha he Pl t m y 'be'sp into. engagement with the bead recess 3 byinserting it through the larger end of the deflector and exerting suffici ent pressure to force i s peripheral edge t e g o v W e it will besecurely retained.

tion is prevented.

I prefer to provide the top plate 4 with a portion of the combustionproducts and deflect them laterally and such openings may be formed bymaking semi-circular may in the plate and deflecting the lips thusformed upwardly at a slight angle. Preferably the lips are reinforced attheir edges by beads 4 formed by the stamping and the plate 4 may bestiffened by a similar bead 4.

If preferred, however, the top plate may be made imperforate as shown inFig. 5.

A modified form of, supporting frame is shownin Fig. 4 which is shown ascomprising a closed loop 6 of wire of a shape corresponding to theelongated shape of the hood to which the upper ends of the wire legs orstandards 6- are connected by welding; In

angle corresponding to the inclination of the hood,and being thereaftercontinued down wardto and terminating in flue ring engagmg means.

In testimony whereof, I aflix my signature.

this form, the top plate isdesigned to rest directly on the ring and beheld against lateral displacement by the engagement of the ring with thehood wall. Two of the legs are provided at their lower ends with Sshapedbends a to engage the edge of the ring,while the other is provided atitslower end with aninward horizontal extension at? v having a downwardlyturned inner end a this elongated horizontal extension adapting thesupport to different sizes of flues without bending the legs.
